Activision has released a trailer introducing the Nazi Zombies of Call of Duty: WWII. But these zombies, Sledgehammer Games boss Glen Schofield said, are going to be quite a bit different from their predecessors. Players will embark on a chilling and mysterious journey through a snowy Bavarian village in Mittelburg, Germany, as they attempt to recover priceless works of art stolen by the Axis powers in World War II.
